Transport Layer Security / Secure Sockets Layer explained
TLS/SSL is what puts the 'S' in HTTPS and the padlock in your browser. When you connect to a secure website, TLS establishes an encrypted channel so that everything exchanged — logins, payment details, form data — is scrambled and unreadable to anyone intercepting it along the way. SSL is the older name; TLS is the modern, secure successor, though the terms are still used interchangeably.
Behind the scenes, TLS relies on PKI and digital certificates to both encrypt the connection and verify that you're actually talking to the legitimate server, not an impostor. The same protocol secures far more than websites — it also protects email transmission, VPN connections, APIs, and cloud-service traffic.
Why TLS/SSL matters for your business
Without TLS, data sent over a network travels in plain text that anyone in a position to intercept it — on public Wi-Fi, a compromised router, or a tapped link — can read. For any service handling logins, personal information, or payments, that's an unacceptable exposure and a compliance failure.
TLS also provides authentication and integrity: it confirms the server's identity and ensures data hasn't been tampered with in transit. Today, properly configured TLS is the baseline expectation for any web service, and outdated or misconfigured TLS is itself a security risk that browsers and scanners flag.
Scalogic keeps your connections encrypted
Scalogic ensures your connections use strong, properly configured TLS/SSL as part of our security and infrastructure services. We deploy and renew the certificates behind your websites, email, and remote access, retire outdated protocols, and fix the misconfigurations that scanners and browsers penalize.
Combined with our PKI and encryption management, we keep your data protected in transit and your services trusted — without the surprise outages that expired or broken certificates can cause.
Frequently asked questions
What's the difference between TLS and SSL?
SSL is the older protocol, now deprecated due to security flaws. TLS is its modern, secure successor. The terms are often used interchangeably, but you should be using TLS.
Does TLS protect data at rest?
No — TLS protects data in transit (while it travels). Protecting stored data requires encryption at rest. Scalogic addresses both.
Why do certificates and TLS need management?
Certificates expire and protocols become outdated. Without management, you get outages, browser warnings, and security gaps. Scalogic keeps configurations current.
